===Deciding what machine work to do=== What will the engine be used for? This will be the determining factor on how much you're going to spend. In any case, whether it's a stock replacement swap or a race engine, there are a few things that should be done. #Have your block degreased and magnafluxed. If it passes the magnaflux test, proceed to the next step knowing it to be crack free. #Have it sonic tested; this way you know if the engine block is even worth using. #Have the block checked for core shift. #Most reputable shops can check out the vitals of your engine castings and internal parts. #Have your cylinder walls checked out for roundness and wear to determine the oversize needed. #Have your machinists put a fresh hone on your cylinder walls, unless you plan on doing this step yourself. #If over-boring an engine, use a "torque plate" if at all possible. #Don't forget to have new cam bearings installed if the hot tank ruined them or if they were too worn to reuse. ====What to expect to pay for machining work==== It really varies by where you get the work done and what you actually get done. An average machine shop charges around $90.00 per hour (ca. 2012). A simple head grinding could take as little as a half hour whereas a major bore and hone could take a few hours.
